Venilus, Germ Duplicant

When Venilus enters the battlefield add a +1/+1 counter.
Sacrifice two artifacts: Put two +1/+1 counters
on Venilus and you may have it become a copy
of target creature, except its still a 0/0 and
has this ability.
At the beginning of your upkeep if Venilus has
seven or more counters, transform it.
